pplication filed June 7,

To all whom if may concern Be it known that I, ENRICO MoNGrLLo, a subject of the King of Italy, and a resident of Bradford, in the county of McKean and State of Pennsylvania, have invented certain new and useful improvements in lAmusement Apparatus, of which the following is a specification. l My present invention relates generally .to amusement apparatus, and more particularly to an apparatus in the nature of a rotating seesaw, my object being the provision of a comparatively simple and inexpensive apparatus in the structure of which the parts are balanced and operate in such man ner as to reduce wear to a minimum and make it an easy matter to maintain the same in proper working condition. Y

In the accompanying drawings which illustrate my present invention and form a part of this specification,

Figure lis a top plan view,

Figure 2 is a side elevation,

Figure 3 is a detail perspective view of the shaft driving the eccentrics,

Figure l is a sectional view through one of the eccentrics,

Figure 5 is a detail perspective view of the connecting shaft, and

Figure 6 is a horizontal section taken on a plane between they guide frame and platform.

JReferring now to these figures, and in accordance with my invention, a circular platform 10 is provided at spaced points ytherearound with wheels or rollers 11 disposed upon and traveling on the outer circular track 12 of a lower guide frame 18, the latter being clearly seen in Figure 6 and having a stationary central gear 14 enclosingball or other anti-friction'bearings 15 on which the depending central bearing member 16 of the platform 10 rests so that the rollers 11, the latter of which are preferably of the flanged type to prevent accidental displacement of the platform, may travel easily and without undue friction.

Mounted through the platform 10 is a vertical connecting shaft 17, the lower end of which is provided with a spur gear 18 in mesh with the ring gear 1l of the supporting frame, and the upper end of which shaft Vhas a worm 19 ata point substantially above the platform.

rllhe platformlalso supports the base 2O of an upright framework 21 whose upper cross Speccation of Letters Patent.

bar supports the bearings 23 of the seesaw beams 2li. Framework 21 also has intermediate cross bars 25 at right angles to the upper cross bar 22, said intermediate cross bars supporting bearings 26 for the opposite ends of a shaft 27 having at its center a worm gear 2S with which the worm 19 meshes.

rlhe shaft 27 is provided at opposite sides of its'worm gear 28 with eccentric disks 29, each of which is peripherally grooved to form a seat for its eccentric strap 3() which is connected to the lower end of a connecting rod 31.

By reference to Figure 2 it will be noted that the connecting rod 31 of the two eccentrics are extended to relatively opposite sides of the central plane which runs through the axis of the platform 10, through the shaft 27 and the bearings 23 of the seesaw beams 24, the outer ends of these connecting rods 31 being pivotally connected at 32 to the beams l2st at equi-distant points from the bearings 23 supporting the beam fulcrums.

Each of the seesaw beams 24 is braced by a truss 33, and each thereof is provided at its opposite ends with swivelly supported seats 34 whereby the latter' remain level at all times irrespective of the upward and downward movements thereof.

ln practice the eccentric disks 29 are preferably keyed on the driven shaft 27 as shown in Figure 4, the key being indicated at 35, and a motor of any suitable type may be mounted directly on the platform 10 and connected in any suitable manner to the upright connecting shaft 17 so as to rotate the latter. As this shaft rotates, its lower gear 18, meshing with the stationary ring gear 14 of the supporting frame 13, causes rotation of the platformv 10. At the same time the worm 19 at the upper end of shaft 17 rotates the driven shaft 27 which, through its eccentrics, causes swinging movement 0f the seesaw beams 24 on their fulcrums in the bearings 23.

In this way a combined rotation and swinging or seesaw movement is brought about in a simple effective manner to the amusement of those seated in the seats 34:, and it is quite obvious that in view of the manner in which the several parts are mounted, in particular the balancing of the power connections leading to the seesaw beams, the motion will be easy and uniform, vibration being reduced to a minimum, and

seats at their outer ends, a driven fshait mounted in the framework below the said bearings and alined with the latter above `the axis of the platform, a vertical shaft lmounted through the platform having a gear at its lower end engaging the stationary gear of the supporting frame and also having geared connection at its upper end with the first mentioned shaft, eccentrics secured on the first mentioned shaft, and connecting rods leading from said eccentrics and `connected to the seesaw beams at equi- .distant points upon relatively1 opposite sides of the fulcrums of the latter.

2. An amusement apparatus including a Supporting frame, a platform rotatable on said frame, an upright framework secured on and rotating with said platform, seesaw beams ulcrumed on said framework, seats at the outer ends-of said beams, a shaft journaled in the said frameworkV in vertical alinement with the axis of the platform and the fulcrums oi said beams and having operative connections with the seesaw `beams engaging the latter at relatively opposite sides of their fulcrums, anda vertical shaft journaled through the platform having geared connection at its upper end with the irst mentioned shaft and having a gear at its lower end in engagement with the fgear of the sup porting 'frame as described.
